Various types of glue or adhesive have been used to fix such sleeves or tapes onto grips and to bind such sleeves together. As shown in FIG. 1, a grip sleeve 1 includes an outer sleeve piece 10. The outer sleeve piece 10 major-axially and peripherally covers an inner sleeve piece 20. The inner sleeve piece 20 has one end jutting out the outer sleeve piece 10 and folded toward the outer peripheral wall of the outer sleeve piece 10 to form a shield 21. Therein, when the outer sleeve piece 10 peripherally covers the major-axial peripheral wall of the inner sleeve piece 20, adhesive or glue is applied to bind the sleeve pieces 10, 20 firmly for preventing the two from separating.

In practical manufacturing process, the adhesive or glue first adheres to the major-axially directed outer peripheral wall of the outer sleeve piece 10 of the grip sleeve 1 with its one adhesive surface, and then has the release paper or protective film covering it's the other adhesive surface removed, so as to expose its second adhesive surface. Then the inner sleeve piece 20 is major-axially mounted around the outer sleeve piece 10, with its one end jutting out the outer sleeve piece 10. At last, external force is applied to the peripheral wall of the outer sleeve piece 10 to make the two sleeve pieces 10, 20 come close and adhere to each other. However, after the process of removing the release paper or protective film to expose the second adhesive surface of the outer sleeve piece 10 of the grip sleeve 1 an additional jig or technique has to be implemented to help mounting, binding or adherence the sleeve pieces 10, 20, making the subsequent processing demanding and troublesome.
